Abstract

PURPOSE:To contrive the improvement in the magnetic characteristics of a rubber magnet and a plastic magnet by annealing magnet plumbite magnetic powder at prescribed temperature higher than Curie point and lower than predetermined temperature to readily remove magnetic strain in the magnet. CONSTITUTION:In order to remove the magnetic strain of the magnet plumbite magnetic powder used for a plastic magnet or a rubber magnet, the magnet plumbite magnetic powder is annealed at prescribed temperature higher than Curie point and lower than 950 deg.C. In this manner, the magnetic strain of the magnet can be readily removed to improve the magnetic characteristics of the rubber and plastic magnets.
